WasmGPU.math¶
Summary¶
WasmGPU.math exposes lightweight JavaScript wrappers for matrix, quaternion, and vector operations.
The object contains three namespaces: mat4, quat, and vec3.
These APIs are convenience utilities for CPU-side math in setup and interaction code.
Syntax¶
Parameters¶
This accessor does not take parameters.
Returns¶
{ mat4, quat, vec3 } - Math helper namespaces exposed by WasmGPU.
Type Details¶
type Mat4 = number[]; // expected length: 16 (column-major)
type Quat = number[]; // expected length: 4 ([x, y, z, w])
type Vec3 = number[]; // expected length: 3 ([x, y, z])
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const model = wgpu.math.mat4.translate(wgpu.math.mat4.identity(), [2, 0, -5]);
const q = wgpu.math.quat.fromAxisAngle([0, 1, 0], Math.PI / 3);
const dir = wgpu.math.quat.toRotation(q, [0, 0, -1]);
const n = wgpu.math.vec3.normalize(dir);
console.log(model, q, n);
